formic acid is stronger than the acetic acid.give reason?

In formic acid,H atom hsving I =0 is attached with -COOH group which does not change the ionisation of the acid. But, -CH3 group attached with -COOH group in CH3-COOH has +ve inductive effect and so reduces the ionisation of acetic acid. Hence,formic acid is stronger acid than acetic acid.

Acidity can be analyzed by examining the corresponding conjugate base vis-a-vis study of available/active electronic effects on its stability.
